Genome-wide analysis of gene expression in mLTC-1 cells following siRNA-mediated Gata4 inhibition

ABSTRACT: The effects of Gata4 inhibition on global gene expression in mLTC-1 cells was analysed. Using microarray analysis we identified a set of genes that are downregulated or upregulated following siRNA-mediated silencing of Gata4 in the murine Leydig tumor cell line mLTC-1. Among the downregulated genes were enzymes of the androgen biosynthetic pathway. mLTC-1 cells were transfected with non-targeting (NT) siRNA and Gata4 siRNA respectively. 72h post transfection cells were lysed and RNA was extracted. n=3 of each sample group; control samples are samples 3-6 (mLTC-1 cells treated with non-targeting siRNA)

Transcription factor GATA4 is expressed in somatic cells of the mammalian testis. Gene targeting studies in mice have shown that GATA4 is essential for proper differentiation and function of Sertoli cells. The role of GATA4 in Leydig cell development, however, remains controversial, because targeted mutagenesis experiments in mice have not shown a consistent phenotype, possibly due to context-dependent effects or compensatory responses. We therefore undertook a reductionist approach to study the ...[more]

Receptor-independent ectopic activity of PROLACTIN predicts aggressive lung tumors and indicates HDACi-based therapeutic strategies.

Project description:Aim: PROLACTIN (PRL), normally produced by the pituitary gland, acts through its receptor (PRL-R) to initiate a signalling cascade to the genome. PRL can also be produced by cancer cells and become oncogenic by stimulating its receptor following an autocrine or paracrine route. Here we investigated the oncogenic activities of PRL in lung cancer. Results: PRL is ectopically activated in a subset of very aggressive lung tumours, associated with a rapid fatal outcome, in our cohort of 293 lung tumour patients as well as in an external independent series of patients. An investigation of the molecular basis of PRL adverse effects surprisingly showed an absence of PRL-R expression in the vast majority of PRL-expressing lung tumours. Additionally, a detailed analysis of the ectopically expressed PRL transcripts in lung tumours and cell lines revealed systematic alterations of its first exons encoding the signal peptide. Finally, the transcriptomes of two PRL expressing lung cancer cell lines, with or without silencing of PRL, showed that PRL directly or indirectly sustains the expression of a group of genes that are frequently up-regulated in a variety of unrelated cancers. Interestingly, the gene signature repressed by PRL ectopic expression in lung tumour cells is also specifically up-regulated by HDAC inhibitor treatment or HDAC1/2/3 knock-down. Innovation and conclusion: Altogether, this work sheds lights on the poorly understood impact of the recently-shown large-scale out-of-context gene activity in cancer and also suggests that PRL-expressing aggressive lung cancers could be particularly responsive to a HDAC inhibitor-based treatment. Total RNA was extracted from two small cell lung carcinoma (SCLC) cell lines expressing PRL (H146 and h524: si control) or not (siPRL) and the differentially expressed genes. Five replicates were analysed for each of the four conditions.

RNA-seq to investigate YBX3 siRNA knockdown in HeLa cells

Project description:This study identifies the transcriptomic effects of YBX3 depletion after 2 days of siRNA knockdown. Unspecific siRNA and untreated cells were used as controls. The cells were grown in SILAC media and the effects on protein levels were measured by mass spectrometry. Also an eCLIP (E-MTAB-5888) experiment was performed to identify RNA targets of YBX3.

Whole proteome analysis of leukocytes isolated from peripheral blood of patients with sex determination defects and germ cell tumors, occurred in Swyer and CAIS.

Project description:The ability to transmit genetic information through generations depends on preservation of genome integrity. Genetic abnormalities affect cell differentiation, causing tissue specification defects and cancer. We addressed genomic instability in individuals with Differences of Sex Development (DSD), characterized by gonadal dysgenesis, sex reversal, infertility, high susceptibility for different types of cancer, especially Germ Cell Tumors (GCT), and in men with testicular GCTs. We analyzed the whole proteome of leukocytes and confirmed it with immunoblotting and quantitative PCR analysis. Additional data from tissue biopsies strengthen our observations in peripheral blood. In particular, the analysis of leukocytes and dysgenic gonads uncovered DNA damage phenotypes, supported by changes in DNA damage response mechanisms: altered autophagy and innate immune response, suppressed TP53-dependent DNA repair.

RNA-Seq of Flp-In T-REx 293, two clones of CRISPR-Cas9 mediated knockout of CASC3 and further CASC3 depletion via small interfering RNAs

Project description:We report two knockouts of the CASC3 (Barentsz, MLN51) gene and further depletion of gene expression with small interfering RNAs (siRNAs). CASC3 is a component of the exon-junction complex (EJC) which is deposited upstream of splice junctions on the mRNA. The EJC core and peripheral interacting factors are involved in RNA splicing, export, translation and nonsense-mediated decay. Contrasting to the other factors that form the exon-junction complex, CASC3 individual role on these processes was relatively poorly understood in the literature. To further elucidate the role of CASC3 in these processes we have established 2 different CRISPR-Cas9 genetic knockouts (KO) of CASC3. We extracted the total RNA by using the NucleoSpin RNA Plus kit (Macherey-Nagel), and performed ribosomal depletion and strand-specific library preparation with the TruSeq Stranded Total RNA protocol with Ribo-Zero Gold. Sequencing of the KO clones as well as the KO clones treated with CASC3 siRNA was carried out with the Illumina NovaSeq6000 sequencer with 2×100bp, targeting approximately 50 million read-pairs per sample. By studying the RNA-Seq of the 4 conditions, one with minimal CASC3 expression (condition H) or and three with complete depletion of the protein expression (conditions H-KD, T, T-KD), we observed the up-regulation of known and novel nonsense mediated decay substrates, thus establishing CASC3 as a critical factor for efficient nonsense mediated decay of certain transcripts.
